SPECIFICATION forming part of Letters Patent No. 406,619, dated July 9,1889. Application filed April 23, 1889. I Serial No. 308,274- (Nomodel.)

'To all whom it may concern:

Be it known that I, J OHN C. BENTHALL, of Schulenburg, in the county ofFayette and State of Texas, have'invented a new and Improved Cultivator,of which the following is a full, clear, and exact description.

My invention relates to an improvementin cultivators, and has for itsobject to provide a cultivator of simple and durable construction,capable of being adjusted laterally to any width and vertically to anydesired height.

The invent-ion consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters and figures of referenceindicate corresponding parts in all the views.

Figure 1 is a plan view of the cultivator. Fig. 2 is a section on line yy of Fig. 3. Fig. 3 is a section on line as 0f Fig. 1; and Figs. 4 and 5are vertical sections taken respectively upon lines w and z of Fig. 3. l

In carrying out the invention the frame of the machine consists, first,of two spaced beams 10, boltedor otherwise secured together to form thefront cross-bar A, upon the front of which two metal blocks or boxes 11are secured, one near each end, having a vertical semicircular groove intheir front face, and in the groove of each block a tube 12 isperpendicularly held by an eyebolt 18, passing over the tubes throughthe block, which eyebolts also pass between the beams through astay-plate 14 upon the opposite side of the beams, the projecting endsof the. eyebolts being threaded and provided with a By means of thisconstruction it will be readily observed that the position of the tubeswith respect to the length of the beams may be changedat will byloosening the nuts and sliding the blocks toward or away from thecenter.

The second portion of the frame consists of two spaced longitudinalbeams 15, having attached to, the forward end of each a supporting-rod16, the upper ends of which rods are carried perpendicularly upwardthrough and beyond the respective tubes 12. The lower extremities of therods are preferably bifurcated, and through their upper extremities aspring key or bolt is passed in contact with the upper face of thetubes. This arrangement gives botll vertical and lateral movement to thesaid longitudinalbeams. To the rear end of the beams 15 the handles 16are secured.

The third portion of the frame consists of the axle B, which is arched,comprising two transversebeams 1'7, longer than the forward beam 10, andarranged in. similar manner upon the rear face of the axle cross-barthus formed two blocks or boxes 18 are secured,

one near each end, which blocks orboxes are essentially similar inconstruction to the boxes 11 of the forward cross-bar, and in contactwith each block or box a vertical tube 18 is held secured in like mannerto the forward tubes 12.

The vertical member of an angled spindle 19 is inserted in each of thetubes 18, having a key or bolt passed through its upper projecting end,and upon the horizontal member of the said spindle the drive-wheels 20are loosely mounted.

From the lower end of the vertical member of each spindle a horizontalarm 21 is forwardly projected, each arm being connected by a chain 22with a bolt 23, secured in each of the longitudinal beams 15, whichbeams are preferably provided with a series of boltapertures, wherebythe posit-ion of the bolts may be changed to accommodate the adjustmentsof the machine. The shafts or thills 24 are secured to the beams 15 andpass forward through the axle cross-bar.

Slightly to the rear of the axle, upon the inner face of eachlongitudinal beam, a disk 25 is secured, which disks are in transversealignment and provided upon their opposed faces with a series of radialteeth. The teeth of each disk 25 are adapted to engage with the radialteeth of a second disk 26, havinga semicircular groove in its inner faceto receive and accommodate a vertical tube 27. Through each tube 27 therod or standard 28 of the share-carrier is upwardly passed, the lowerend whereof is curved, as shown at 29 in Fig. 3, to receive the variousshares or blades 30 usually employed in cultivators. Above each tube 27a thimble-shaped casting or ring 31 is entered upon theupper projectingend of the standards 28, as shown in Fig. 3, and secured thereto by asuitable set-screw, which thimble is of two interior diameters, to restupon the upper end of the tube and overlap the same. A similar thimbleis employed at the lower end of the tubes. By this construction theentire strength of the tubes and standards is combined. The top of eachstandard is provided with an arched or curved iron 31, rigidly attachedthereto, by means of which irons the two opposed standards areconnected. One iron overlaps the OtllOllfOlflllll lg a complete arch,and in order that when the other portions of the machine are adjustedlaterally the arch may be adjusted to .correspond each member of thearch is provided with a registering-slot 83, as shown in Fig. 1, and asuitable bolt is passed through the slots. A sleeve or band 34 is alsoemployed to clamp the two members togethers.

A second set of arched share or blade standard-irons D are located tothe rear of the set 1), above described, being attached to the outerface of the longitudinal beams 15, and as the two sets are identical inconstruction I apply the same figures of reference to both. v

When the machine is used as a walkingcultivator, it is guided bycarrying the handles either to the right or left. When employed as ariding cultivator, a lever 35 is utilized for this purpose fulcrumedupon the axle-arch near one end and connected by a link and rod 36 and37 or equivalent device with the opposite longitudinal beam 15, as shownin Fig. 1.

In working crops of considerable height the axle-arch may be readilyraised to any desired height by slacking up the nuts upon the eyeboltsand lowering the tubes upon the forward cross-bar, thus keeping the longitudin al beam s at the same height.

The boxes seating the tubes ofthe axle may be placed either before orbehind the latter, as it is preferable to have them in front whenwalking and behind when riding.

The tubes and grooved or contacting disks of the arches D and I) areseen red to the longitudinal beams, preferably by eyebolts, asillustrated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a cultivator, the combinatio11,witl1a forward cross-bar, tubeslaterally and vertically adjustable upon the same, a rod held in each ofsaid tubes, and spaced longitudinal bodybeams having one end secured tosaid rods, of an axle cross-ba'r,tubes vertically and laterallyadjustable upon said axle-bar, an angled spindle held in each tubecarrying a drive-wheel, and a link-connection between the spindles andbody-beams, substantially as shown and described.

2. In a cultivator, the combination, with a forward cross-bar, tubeslaterally and vertically adjustable upon the same, a rod held in eachtube, and spaced longitudinal bodybeams secured at one end to said rods,of an axle cross-bar, tubes vertically and laterally adjustable thereon,an angled spindle held in each tube carrying a drive-wheel, alink-connection between the spindles and body-beams, and laterally andvertically adjustable arched blade or share carriers secured to the bodybeams, substantially as shown and described.

3. In a cultivator, the combination, with a forward cross-bar, tubeslaterally and vertically adjustable upon the same, a rod held in eachtube, and spaced longitudinal bodybeams secured to the said rods, of anaxle cross-bar, tubes vertically and laterally adjustable thereon, anangled spindle held in each tube carrying a drive-wheel, alink-connection between thespindle and body-beams, laterally andvertically adjustable arched blade or share carriers secured to thebodybealns, a lever fulcrumed upon the axle crossbar, and apitman-connection between the lever and opposite body-beam,substantially as shown and described.

4. In a cultivator, the combination, with a swinging frame, of transversely-ali gning tubes secured to the side beams of the frame, astandc rd passed upward through each tube curved at the lower end toreceive a share or blade, a thimble provided with two interiordiameters, a set-screw uniting the tubes and standards, and curved barssecured to the upper end of each standard, united to form alaterally-adj ustable arch-connection, substantially as shown anddescribed.

5. Ina cultivator, the combination, with a swinging frame and diskshaving one radiallytoothed face secured to the side beams of the frame,a second grooved and toothed disk contacting with the frame-disk, atubedetachably clamped to the grooved disks and frame, a share carryingstandard passed upward through each tube, a thimble provided with twointerior diameters, a set-screw clamping the tubes to the standards, anda curved bar rigidly secured to the upper end of each standard, saidbars being united by a laterally-adjustable connection, substantially asshown and described.
